TIE-PLATE.

Specification of Letters Patent.

Application filed December 9, 1909. Serial No. 532,154.

To all whom it may concern:

Be it known that I, WVILLIs MoKEn, a resident of Elyria, in the countyof Lorain and btate of Ohio, have invented a new and useful Improvementin Tie-Plates; and I do hereby declare the following to be a full,clear, and exact description thereof.

My invention relates to tie-plates, and to what are generally known astie-plates for railway rails.

The object of my invention is to provide a cheap, simple and efiicientform of a tieplate, which can be rolled from a metal bar or billet, suchas steel, will enable it to be produced in a rapid, easy and convenientmanner,and will provide such a' form as .Will enable the rail to havesuflicient play when in place thereon, while at the same time allowingfor the proper supporting of the rail thereon and maintaining the rail"and plate in their proper positions.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallyset forth and described and particularly pointed out in the claims.

Toenable others skilled in the art. to which my invention appertains toconstruct and use my improved tie-plate, I will describe the same morefully, referring tothe accompanying drawing, in which Figure 1 is an endelevation of my improved tie-plate showing the same in position with therail and tie. Fig. 2 is a top plan view of the plate. Fig. 3 is'a detailView of another form of my improved plate.

Like symbols of reference herein indicate like parts in each of thefigures of the drawing.

. As illustrated in the drawing, 1 represents my improved tie-plate,which is preferably rolled from a bar or billet of metal, such as steel,into lengths, and then such lengths are to form such plate. Thistie-plate 1, as shown in Figs. 1 and 2 when so rolled or formed isprovided with the body portion 2 having longitudinal grooves ordepressions 3 in the upper face of the same to form broad railbe'aringsurfaces 4 on said face, and with longitudinal depending ribs or flanges5 on the lower face of said body, which are preferably formed oftriangular sha with sharpened edges for entering the tie 1n the usualmanner andare so locatedas to come under the bearing surfaces 4: and atthe outer sides of the depressions The tie-plate 1 is also provided witha. rail-abutting shoulder 6 ateach side of the same, and

such shoulders extend up from and at the I Patented Apr. 12, 1910.

and forming part of said shoulders are the longitudinal spike-bearingportions? which have their top surfaces 7 'formed on a downward inclinefrom said shoulders and on the same plane as the top of the flange b ofthe 'rail a to be employed therewith. After the plate 1 has been soformed, spike-holes '8 are formed therein in any suitable manner, whichextend through the bearing portions 7 on the plate for the reception ofthe shanks 9 of the screw-spikes 10, and such holes are in a verticalline and of sufiicient size by elongating the same, so that such spikesmay enter the tie c employed therewith at an incline toward the centerof the plate and under the rail a, when the parts are in osition.

The made 11 on the spikes 10 are pro vided with the flat circularsurface 12 on their under sides, so that when the plate 1 is in positionon the tie a, as shown in Fig. 1 and the rail 4; is in position on thebearing surfaces 4 of said plate and between the shoulders 6 thereon,the spikes 10 when screwed to the position shown, will enable the outerand side portions of the flat surfaces 12 on their heads to be broughtinto surface contact with and bear against the inclined surfaces 7' onthe bearing portions 7 of the plate, while the inner portions of saidflat surfaces on said spike-heads will extend over and slightly abovethe top of the rail flange Z2 and form a clearance or space 13 betweensaid heads and flange, as shown .and in this case the head 11 of thespike is provided with an inclined under surface I the clearance orspace 13 between the spikehead and rail flange with a line contactbetween said head bear portion 7".

Various other modifier. ons and changes in the design and otion of myimproved tie-plate may orted to without deparcing from s o of theinvention or sacrificing any of advantages.

It wilithus be seen tiat'my improved tieplate will allow the rail tohave a fixed amount of play when connected to a tieplate and at the sametime the plate will be securely held in position by being firmly fixedto the tie and will permit the rail to move away from the same if sorequired. This form of plate will enable a sufficient amount of contactwith the spike-head, and as the spike would wear away the rail wouldhave the proper play, so as to act to stop the pumping of the ballastand thereby prevent the entrance of the same and dirt into the parts ofthe device, which will thus overcome any undue wearing out of suchparts. it will also be seen that my improved tie-plate can be formed bystraight rolling into lengths for the proper shape required easily andquickly, and such plate can also be formed by other methods or processesandfrom various materials, if desired. The plate so formed will enablesurface or line contact between the head of the spike and the plate, aswell as a complete and substantial support for the hack and sides of thespike-head, and suclrhead will he assured of a good and broad bearing onthe platein any position of the spike. It will further be seen that myimproved tie-plate will provide for a spike bearing surface which israised in a plane parallel to but above the plane or top of the railbase and so constructed that the spike can be drawn down tight on saidsurface and hold the plate tight but will leave a predeterminedlooseness to the rail, while at the same time.

caress such bearing surface can extend around the rear and around bothsides of the center line of the spike, so that such spike can 'be firmlytightened without coming in contact with rail base or flange.

What I claim as my invention and desire I to secure by Letters Patent isl. A tie-plate for rails having a rail abut-- ting shoulder at the sideof the same and forming a spike bearing surface extendingabove the topof the rail flange so that the spike can be securely drawn down tight onsaid surface to hold the plate tight and leave a pre-determinedloosencss to the rail. v

2. A ti'e plate for rails having a rail abutting shoulder at the side ofthe same and forming a spike bearing surface which is in a planeparallel to but raised above the plane of the topof the flange of therail base.

3. A tieplate for rails having a rail abutting shoulder at the side ofthe same and forming a spike bearing surface which extends above the topof the rail flange and around the rear and on both sides of the centerline of the spike, so that the spike can be firmly tightened on saidsurface Without coming in contact with the rail flange.

4. A tie-plate for rails having a rail abutting shoulder at the side ofthe same and forming a bearing portion for the head of the spikeextending outwardly from said shoulder and above the plane of the top ofthe rail flange to form a space between said head and flange. I

A tie-plate for rails having a railabutting shoulder at the side of thesame and forming an inclined bearing portion for the head oi the spikeextending outwardly from said shoulder and above the plane of the top ofthe rail flange toform a space between said head and flange.

6. A tie-plate for rails having a rail abutting shoulder at the side ofthe same and forming a bearing portion for the head oi the SPlKB"ext-ending outwardly at a downward incline from said shoulder and abovethe plane of the top of the rail flange to form a space between saidhead and flange.

In testimony whereof, I, the said Wnms Molina, have hereunto set myhand.
